In tional relation between the extension and the using the invention for dispensing cigar lighter tube, the latter may be adjusted vertically to fluids, the diaphragm 26 should be made of a position its lower end in proper relation with the rubber treated to resist the disintegrating action bottom 20. Unit 38 is provided with a depressed of the material. Because of the shiftable mountportion 54 which co-operates with the flange 40 ing for the dispensing tube l8, the tube may be ereach 22.

adjusted to difierent positions to perform 8. skimming action. The air in the container is effectively trapped therein so as not to escape when pressure is applied to the diaphragm.

I provide the element 46 with a bore 56 arranged to receive the open end of the right angular reach 22 by rotating the tube I8 180". Element 46 because of being carried by the flexible diaphragm 26 may be tilted slightly to one side to facilitate insertion of the open end of the With the open end pressed into the bore 46, an eifective closure is provided. The diaphragm 26, element 46 and the tubular extension 62 comprise an integral unit while the element 46 performs a two-fold function, namely, an actuating element for the diaphragm and a closure for the tube l8.

In Figs. 3,4 and 5, I illustrate a different form of closure for the dispensing tube l8. Upon the element 46 I mount a rigid cap 58 which has frictional relation with the element 46 for connection purposes. Cap 58 is provided with an opening 66 for connection with a chain 62 made up of balls '64 interconnected by links 66. One of the balls is housed within the-cap, and the opening 60 is smaller than this ball. The balls 64 underneath the cap and the balls 64 lying against its outer face are connected with their connecting links 66 after assembly'with the cap. To the opposite end of the chain 62 I connect a soft rubber cap 68 having a cavity ID for the reception of the ball 64 at that end of the chain. The cap is provided with a small opening I2 which may be stretched to permit the ball 64 to be pressed into the cavity Ill. Cap 68 is provided with a bore I4 for the reception of the end 22 of the dispensing tube 18.

In Fig. 2, I illustrate the pressure element 46 as being provided with a small air bleed 16. This bleed is covered by the finger when pressure is applied to the diaphragm so as to prevent the escape of air. The bleed provides leakage for air when the cover I2 is screwed down so as to prevent excessive pressure on the liquid, which might force some of it through the dispensing tube. At the same time, the air vent prevents excessive pressure on the material due to expansion thereof incident to a rising temperature.

Without further elaboration, the foregoing will so fully explain my invention that others may, by applying current knowledge, readily adapt the same for use under various conditions of service.
